Since she has passed on, of course I can't ask her and can only speculate but I think she would have reacted with a mixture of humor and curiosity. Humor because I was so new to any feminine experiences I would have been extremely ill at ease with the experience. Curiosity of course would have followed closely because she would have been closely checking out how I would have handled it. I can only say, it I had handled it smoothly, it would have cost me dearly in our relationship in the near future. She would have wondered I am sure how I was able to handle it so naturally. It didn't matter because she ended up talking with the guy.
You Cyrsti's Condo regulars may recall though I had a chance much later in life a couple times to be a wing person for one of my lesbian friends. Even though it was fun and flattering to do, I was never successful. I think deep down inside I knew it would be one of the few times in my life I would able to interact as a wing person for someone else. If by chance you don't know what a wing person does, she (in my case) was asked to approach another person in a bar and tell them my friend was interested in talking to them.
One way or another, I wasn't successful so I will never really know how the person's I approached truly felt about me. I only know I had come a long way as a transgender woman in the mean time,
Make my wings spicy!
